You do not have to repeat the same include in both .h and .cc files.

https://google.github.io/styleguide/cppguide.html#Names_and_Order_of_Includes
"any includes present in the related header do not need to be included again in
the related cc (i.e., foo.cc can rely on foo.h's includes)."

Yeah, the script I whipped up for automating this simply ensures that we
#include <memory> in all files that mention unique_ptr, without taking
subtleties like this one into account. I'll see if I can make it handle this
case without spending too much time on it.
